/v1/emails no longer filters by status for you

When we first launched Buttondown's API, we actually had three separate email endpoints: /v1/drafts, /v1/scheduled_emails, and /v1/emails, because we had three separate models for emails, drafts, and scheduled emails.

graph TD
    /v1/emails --> Emails
    /v1/drafts --> Drafts
    /v1/scheduled_emails --> Emails

This was an architectural mistake for many reasons, and we combined them into a single backing model, Email:

graph TD
    /v1/emails --> |status=sent,in_flight| Emails
    /v1/drafts --> |status=draft| Emails
    /v1/scheduled_emails --> |status=scheduled| Emails

We eventually realized the error of our ways and combined these, but to maintain backwards compatibility (before we had a versioning system!) we defaulted /v1/emails to have a behavior of only ever showing "real" emails that were in flight or sent.

graph TD
    /v1/emails --> |status=sent,in_flight| Emails
    d["/v1/emails?status=draft"] --> |status=draft| Emails
    s["/v1/emails?status=scheduled"] --> |status=scheduled| Emails

Fast forward three years, and this is still the case for non-obvious and increasingly tenuous reasons. We've cut a new version of the API that removes this little piece of duct tape, such that a call to /v1/emails will return all emails, regardless of status. (And you can still of course filter them by passing in status as a query parameter.)

graph TD
    /v1/emails --> before("Before 2025-06-01")
    /v1/emails --> after("After 2025-06-01")
    before --> |status=sent,in_flight| Emails
    after --> Emails
    d["/v1/emails?status=draft"] --> |status=draft| Emails
    s["/v1/emails?status=scheduled"] --> |status=scheduled| Emails

Pin to an older API version if you need the old default back.
